Interesting update to the power conditioning issues!
So - it turns out that the power in the house in question was DEAD SILENT. The issue was a component in the room that was pumping out RF and also some line noise back into the house circuit - some third party phone system gadget for internet phone service that ties back into the home POTS lines. This in combination with a pair of presonus studio monitors that have a track record for a nasty high Frq hiss lead us down this long road.
Thank you everyone for the fantastic information - I always say the only stupid question is the one you have to ask twice!! I am still keeping my eye out for a honking isolation transformer at local swaps and online so I might build up a power conditioning setup anyway just for the experience if I can find the parts on the cheap.
Take care,
Ewing
